Method and system for providing a brain computer interface

1. A method for providing a brain computer interface comprising:

within a first time window, detecting a first neural signal of a user in response to a calibration session having at least one of a first time-locked component and a first spontaneous component, wherein the first time-locked component comprises a first randomized factor associated with an unexpected modification to a first percentage of a first stimulus of the calibration session, the first stimulus not pre-selected by the user;

generating a user-specific calibration model based on a response of the user to the unexpected modification to the first stimulus captured in the first neural signal;

prompting the user to undergo a verification session within a second time window;

detecting a second neural signal contemporaneously with delivery of the verification session;

generating an output of the user-specific calibration model from the second neural signal;

determining an authentication status of the user based upon the output; and

based upon the authentication status, performing an authenticated action.

2. The method of claim 1 , wherein performing the authenticated action comprises providing visual electronic content to the user at a display associated with the user.

3. The method of claim 1 , wherein performing the authenticated action comprises providing audio content to the user at an audio output device associated with the user.

4. The method of claim 1 , wherein performing the authenticated action comprises performing an action that is customized to preferences of the user.

5. The method of claim 1 , further comprising performing a repeat instance of at least one of the calibration session and the verification session within a time window.

6. The method of claim 1 , wherein performing the authenticated action comprises adjusting a parameter of an environment surrounding the user, by way of a connected device in the environment surrounding the user.

7. The method of claim 6 , wherein the environment is at least one of a physical environment and a virtual environment associated with the user.

8. The method of claim 1 , wherein performing the authenticated action comprises providing personalized digital content to the user.

9. The method of claim 1 , wherein performing the authenticated action comprises at least one of: delivering digital content and adjusting operation of a user device in coordination with detection of a brain state of the user.

10. The method of claim 9 , wherein the brain state comprises an emotional state of the user.

11. The method of claim 9 , wherein the brain state comprises a state of focus of the user.

12. The method of claim 9 , wherein the brain state comprises a state of at least one of overt attention and covert attention of the user.

13. The method of claim 9 , wherein the brain state comprises an alertness state of the user.

14. The method of claim 13 , wherein the alertness state comprises a sleep state of the user.

15. The method of claim 14 , wherein performing the authenticated action comprises adjusting a parameter of an environment surrounding the user, by way of a connected device in the environment surrounding the user.

16. The method of claim 9 , wherein the brain state comprises a neurological health state of the user.

17. The method of claim 9 , wherein performing the authenticated action comprises allowing the user to perform an action, based upon an authorization status of the user to perform the action.

18. The method of claim 17 , wherein performing the authenticated action comprises enabling access of vehicle control functions based upon the authorization status of the user.

19. The method of claim 17 wherein performing the authenticated action comprises authorizing the user to access a computing system.

20. The method of claim 1 , wherein the first time-locked component comprises a first visual stimulus, and wherein the first percentage comprises a percentage ranging from 1%-80%.
